搜索+最优性剪枝. DFS的下一层起点应为当前选择的 i 的下一个,即DFS(i + 1)而不是DFS( cur + 1 ),cur+1代表当前起点的下一个.没想清楚,TLE到死…… #include <cstdio> #include <cstring> #include <cstdlib> #include <algorithm> using namespace std; ; struct node { int t, id; int cnt; ]; };…

这题官方结题报告一直在强调不难,只要注意剪枝就行. 这题剪枝就是生命....没有最优化剪枝就跪了:如果当前连续切割数加上剩余的所有切割数没有现存的最优解多的话,不需要继续搜索了 #include <cstdio> #include <iostream> #include <cmath> #include <cstring> #include <algorithm> # define MAX 33 using namespace std; stru…

对t进行从小到大排序(要记录ID),然后直接dfs. 剪枝的话,利用A*的思想,假设之后的全部连击也不能得到更优解. 因为要回溯,而且由于每次cut 的数目不会超过10,所以需要回溯的下标可以利用一个二进制保存. 由于cut最多30个,所以方案也可以用一个二进制保存. #include<cstdio> #include<cstring> #include<algorithm> #include<iostream> #include<stack>…

题目大意:题目就是描述的水果忍者. N表示以下共有 N种切水果的方式. M表示有M个水果需要你切. W表示两次连续连击之间最大的间隔时间. 然后下N行描述的是 N种切发 第一个数字C表示这种切法可以切多少个水果. 第二个数字表示这种切法所处在的时间. 后C个数字表示此时这种切法所切掉的水果编号. 注意:同时切3个以上才表示连击,一个水果最多只能切一次. 思路:直接暴搜,再去加剪枝. #include <iostream> #include <cstdio> #include <…
